Abstract (en)

[origin: ES474501A1] A thermoplastic moulding composition comprising a polymer mixture of (A) 25 to 95% by weight of a graft polymer of 70 to 30% by weight of a mixture of styrene (95 to 50% by weight) and acrylonitrile (5 to 50% by weight) on 30 to 70% by weight of polybutadiene or a butadiene-styrene copolymer, and (B) 5 to 75% by weight of a terpolymer containing 10 to 30 parts by weight of acrylonitrile, 7.5 to 15 parts by weight of maleic acid anhydride, and 82.5 to 55 parts by weight of styrene in copolymerized form.
